RELEASING-HOOK.

To all whom it may concern:

Be it known that I, CLAYTON D. REES, a citizen of the United States,residing at Medford, in the county of Jackson and State of Oregon, haveinvented certain new and useful Improvements in Releasing Hooks, ofwhich the following is a specifi cation.

This invention relates to releasing hooks designed more particularly foruse on load. binders, and one of the principal objects of the inventionis to provide a hook which can be quickly released for dumping the load.

Another object of the invention is to provide a releasing hook having aloop through which the chain extending around the load will freely slideto tighten said chain around the load, said hook having a pivotedreleasing member and a spring for holding said releasing member inposition to permit the load to be lifted, said spring being providedwith a tripping cord, by means of which the releasing member may bedisconnected to dump the load.

These and other objects may be attained by means of theconstructionillustrated in the accompanying drawing, in which,

Figure l is a side elevation of the load binder provided with areleasing hook made in accordance with my invention, said load binderbeing shown in position for being lifted. Fig. 2 is a side elevation andpartial section of the releasing hook in its open position with aportion of the sling chain extending through the loop of the hook.

Referring to the drawing the numeral 1 designates a chain designed to beused as a sling for surrounding a load 2 of hay or other materialdesired to be lifted and dumped.

My releasing hook is provided with a loop 3 through which one end of thechain 1 is passed and through which said chain freely slides. Extendingat an inclination from the loop 3 is a shank 1, said shank having abifurcated end 5, said shank being slightly curved as at 6. Pivoted inthe bifurcation 5 is a releasing member 7, said member having aprojection 8 which is designed to carry the link 9 at the end of thechain out of the hook when the releasing member is disconnected fordumping the load. The releas- Specification of Letters Patent.

Application filed August 25, 1910.

Serial No. 578,882.

ing member 7 is pivoted upon a pintle 10 and the outer end of saidreleasing member is beveled as at 11 to ride underneath a curved spring12. The spring 12 is secured by means of a screw 13 to the shank 4: ofthe hook and is provided with an opening 1a, through which the upper endof the releasing member 7 extends when the hook is in its lockedposition. A tripping cord 15 is secured to a ring 16 formed on the outerend of the spring 12.

The operation of my invention may be briefly described as follows: Thesling chain is passed around the load and connected to the releasinghook. The releasing member 7 is thrown up and engaged with the opening14 in the spring 12. When the load is lifted the chain freely slidesthrough the loop 3 of the hook to bind the load. When it is desired todump the load the cord 15 is drawn upward and the releasing member 7 ismoved upon its pintle to the position shown in Fig. 2, the projection 8serving to throw the link 9 out of the hook.

From the foregoing it will be obvious that a releasing hook made inaccordance with my invention is simple in construction; reliable andeflicient in use; can be manufactured at low cost and cannot readily getout of order.

I claim:

A releasing hook for load binders comprising a loop through which asling chain may freely slide, a shank extending at an angle to saidloop, said shank being curved and bifurcated, a releasing member pivotedin the bifurcations of said shank, said releasing member having aprojection at one end and beveled at the opposite end, a springreleasing device consisting of a flat metal spring secured to the shankof the hook and provided with an opening through which the beveled endof the releasing member is designed to pass, and a tripping cord connected to said spring for tripping the releasing member.

In testimony whereof I affix my signature in presence of two witnesses.

CLAYTON D. REES.
